Internet world-wide community already got thousand of smart PCs, software and hardware were extremely good enough to handle an application either its online or offline. All we need from the public of network carriers is reliable and high-bandwidth transport. The reason why we need Next Generation Network is because: 1. The Service provider’s business is increasingly become a commodity business. They are being forced to compete by price for ever-shrinking profit margins. In the mean time, competitors are offering more sophisticated services to skim off the incumbent high-margin customers. If the public network carriers want to prosper in the new millennium, they must find ways to add value to their transport services. Next Generation Network advance skill will help them to retain their key customer and expend their addressable markets into new areas. 2. The major thrust of traditional network service providers has been to offer the mass market basic transport of information between end users, with various value-added capabilities.

Ø Application-specific service. Ø Content provision service that provide or broker information content. Ø Internetworking service for interaction with other types of applications, services, networks, protocols, or formats.

As multiple carriers, service provider, equipment vendors, and other business entities all become involved in providing service to end user, federated network and business system will become increasingly important. The service is about: Ø Multimedia services – allow multiple parties to interact using voice, video and data. Ø Data (Connectivity) services – allows for real-time establishment of connectivity between endpoint, along with various value-added features.
